Night vision devices are tools that allow people to see in low-light conditions. They work by amplifying available light, such as moonlight or starlight, to create a clearer image. These devices are commonly used by military personnel, wildlife observers, and security professionals to enhance visibility at night. There are different types of night vision devices, including night vision goggles, monoculars, and binoculars. Some advanced models use thermal imaging technology, which detects heat emitted by objects, making it possible to see in complete darkness. These devices are essential for various applications, from surveillance to outdoor adventures.
